Abstract
ABSTRACT Hyatt, M.W.; Anderson, P.A., and O'Donnell, P.M., 2016. Behavioral release condition score of bull and bonnethead sharks as a coarse indicator of stress. Capture and handling stress can induce acidosis and sometimes mortality in sharks. To approximate physiological condition after capture, fisheries researchers may use a behavioral health assessment at release. The goal of this study was to assess the efficacy of the behavioral release condition score (BRCS) in estimating the physiological stress response. The score was tested against changes in acid-base, blood gas, and metabolite analytes (pH, partial pressure of CO2, and lactate) and factors known to influence those analytes (species, capture and handling time, and water temperature) among wild-caught bull (Carcharhinus leucas) and bonnethead (Sphyrna tiburo) sharks. After gill net capture, sharks were processed for tagging, morphometrics, and blood sampling. Blood was sampled immediately before release. At release, a BRCS was assigned as good...
